Description

Compared with other compounds in its class, the molecular weight of 214.65 g/mol gives 6-Amino-3-ethylbenzo[d]oxazol-2(3H)-one hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-Amino-3-ethylbenzo[d]oxazol-2(3H)-one hydrochloride (CAS 1269087-70-8) is a high-purity analytical reference standard with the molecular formula C9H10N2O2HCl and a molecular weight of 214.65 g/mol.

Structurally, 6-Amino-3-ethylbenzo[d]oxazol-2(3H)-one hydrochloride (C9H10N2O2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 214.65 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
